Assertion Failure in fsevents When Using @pandacss/eslint-plugin with eslint-plugin-jsx-a11y and ESLint Cache

[taichi221228]

Environment:

• Node.js: 22.3.0
• pnpm: 9.12.1
• ESLint: ^9.13.0
• eslint-plugin-react: ^7.37.2
• eslint-plugin-jsx-a11y: ^6.10.1
• @pandacss/eslint-plugin: ^0.2.0

Description:

In a pnpm environment using ESLint's Flat Config with a React setup, I encounter an assertion failure in fsevents when running ESLint multiple times with the --cache option. This occurs specifically when using both @pandacss/eslint-plugin and eslint-plugin-jsx-a11y together.

Error Message:

eslint --cache .

Assertion failed: (napi_create_external(env, fseenv, fse_environment_destroy, NULL, &result) == napi_ok), function fse_environment_create, file fsevents.c, line 87.
[1]    54618 abort      eslint --cache .

Observations:

• The issue does not occur when using either plugin individually.
• When @pandacss/eslint-plugin is configured, the error only occurs with the --cache option.
• Simply importing @pandacss/eslint-plugin without configuring it causes the error, even without the --cache option.

---

Steps to Reproduce:

1. Configure ESLint with @pandacss/eslint-plugin:

   import pandaPlugin from "@pandacss/eslint-plugin";
   
   export const pandaConfigs = [
     {
       plugins: { "@pandacss": pandaPlugin },
       rules: pandaPlugin.configs.recommended.rules,
     },
   ];

2. Run ESLint without cache (No Error):

   eslint .
   
   /path/to/src/App.tsx
     8:7  warning  Unnecessary debug utility  @pandacss/no-debug
   
   ✖ 1 problem (0 errors, 1 warning)

3. Run ESLint with cache (Error Occurs):

   eslint --cache .
   
   /path/to/src/App.tsx
     8:7  warning  Unnecessary debug utility  @pandacss/no-debug
   
   ✖ 1 problem (0 errors, 1 warning)
   
   Assertion failed: (napi_create_external(env, fseenv, fse_environment_destroy, NULL, &result) == napi_ok), function fse_environment_create, file fsevents.c, line 87.
    ELIFECYCLE  Command failed.
   [1]    37634 abort      pnpm lint.cache

4. Importing Without Configuration (Error Occurs Without Cache):

   // The error occurs just by importing without setting up the plugin.
   // eslint-disable-next-line @typescript-eslint/no-unused-vars
   import pandaPlugin from "@pandacss/eslint-plugin";
   
   export const pandaConfigs = [];

   eslint .
   
   Assertion failed: (napi_create_external(env, fseenv, fse_environment_destroy, NULL, &result) == napi_ok), function fse_environment_create, file fsevents.c, line 87.
   [1]    37161 abort      eslint .

Additional Information:

• The issue seems related to the interaction between @pandacss/eslint-plugin, eslint-plugin-jsx-a11y, and ESLint's caching mechanism.
• Removing either plugin or disabling cache prevents the error from occurring.
• The error points to an assertion failure in fsevents, specifically in fsevents.c at line 87.

Behavior:

Expected:

• ESLint should run without errors when both plugins are used together, regardless of the cache option.

Actual:

• ESLint aborts with an assertion failure in fsevents when both plugins are used together with the cache option enabled.

Request:

• Assistance in identifying the cause of this issue and a potential fix or workaround.

@taichi221228 I could not reproduce this

From what I know; fsevents is a macOS-only library used to handle file system events.

You could try removing node_modules and reinstalling.
Or rebuild modules with pnpm rebuild

Otherwise it could be that your node version is incompatible with version of fsevents in project.

These are where it's used

@anubra266 Thank you for your help.

After trying various things, I was able to resolve the issue by deleting the mise shims and ~/.cache/node/corepack/v1/pnpm/9.12.1/**.

As you mentioned, it seems the inconsistency between Node.js and pnpm was the cause.
